Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of carton processing equipment, specifically to a carton folding and creasing depth adjustment mechanism, which is suitable for creasing processing of packaging materials such as corrugated cartons and cardboard boxes. Background Technology
[0002] Cardboard boxes are containers widely used in logistics, warehousing, and product packaging. They are typically made of corrugated cardboard or linerboard and are lightweight, pressure-resistant, and recyclable. In cardboard box manufacturing, crease marking (also known as creasing) is a key process. Its function is to create predetermined creases on the cardboard surface for precise subsequent folding. Good creasing ensures square corners, reduces the risk of bursting, and improves packaging efficiency and finished product strength.
[0003] Currently, most common creasing devices use fixed pressure rollers or shim adjustment structures. The same equipment is difficult to adapt to cardboard of different thicknesses. When adjusting, the machine needs to be stopped to disassemble the pressure rollers or add or remove shims to adjust the creasing depth, which is inefficient. In addition, most existing creasing devices are unidirectional, which requires multiple creasing processes to complete the process. This is not only time-consuming, but also troublesome to debug. Utility Model Content

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0024] Example 1:
[0025] As per the instruction manual Figure 1-4 As shown, a carton folding and pressing depth adjustment mechanism includes a first base 1, a second base 2, a pressing wheel bracket 3, and an adjusting screw 4. The first base 1 and the second base 2 are provided with multiple elongated mounting holes on both sides for connecting the first base 1 and the second base 2 to a carton forming device.
[0026] In this utility model, a longitudinal guide sleeve 5 is provided on the first base 1, and the pressure wheel bracket 3 is slidably disposed inside the guide sleeve 5.
[0027] In this utility model, a depth scale 6 is arranged parallel to one side of the guide sleeve 5. The depth scale 6 is a laser-engraved scale. A corresponding indicator groove 13 is provided on one side of the guide sleeve 5 located on the depth scale 6. An indicator mark 14 corresponding to the depth scale 6 is provided in the indicator groove 13 of the pressure wheel bracket 3, which is used to check the real-time adjustment distance. A locking screw 16 is provided at the bottom of the guide sleeve 5 on one side of the depth scale 6. The bottom of the locking screw 16 can abut against the side of the pressure wheel bracket 3. The locking screw 16 can be used to position the pressure wheel bracket 3 by interference fit to prevent it from shifting.
[0028] In this utility model, the adjusting screw 4 is set parallel to the guide sleeve 5, and one end is connected to the pressure wheel bracket 3 by a threaded connection. The adjusting screw 4 is fixed to the top of the guide sleeve 5 while being able to rotate. A detachable handwheel 9 is provided at the end of the adjusting screw 4 away from the pressure wheel bracket 3. The handwheel 9 is inserted and fixed to the adjusting screw 4, and the insertion point is a rectangular structure.
[0029] In this utility model, the bottom of the pressure wheel bracket 3 is rotatably connected to the upper pressure wheel 7. The pressure wheel bracket 3 is composed of the bottom U-shaped bracket 10 and the upper slider 11. The top of the slider 11 is provided with a threaded hole 12 that cooperates with the adjusting screw 4. The upper pressure wheel 7 is located inside the U-shaped bracket 10. The slider 11 matches the shape of the inside of the guide sleeve 5, and both have rectangular cross-sections.
[0030] In this utility model, a lower pressing wheel 8 protruding from the surface of the second base 2 is rotatably connected above the guide sleeve 5 at the corresponding position. The centers of the upper pressing wheel 7 and the lower pressing wheel 8 are on the same vertical axis, and a pressing gap is formed between the two wheels. The outer rims of the upper pressing wheel 7 and the lower pressing wheel 8 are provided with protruding pressing ridges 15, and pressing is formed by pressing the thread through the pressing ridges 15.
[0031] In a specific implementation, this utility model is installed on the creasing station of a carton forming equipment via a first base 1 and a second base 2, ensuring that the paper feeding direction of the creasing roller is consistent with the paperboard conveying direction.
[0032] During adjustment, rotate the locking screw 16 to release the fixation of the pressure wheel bracket 3, rotate the handwheel 9 to drive the adjusting screw 4 to push the pressure wheel bracket 3 up and down, thereby increasing or decreasing the pressure depth. The real-time adjustment amount is read by the cooperation of the indicator mark 14 and the depth scale 6. After fine-tuning to the required pressure depth, rotate the locking screw 16 to fix the pressure wheel bracket 3.
[0033] When in use, the cardboard passes through the crease gap formed by the upper crease roller 7 and the lower crease roller 8, and the raised crease ridges 15 on both sides work together to create folding creases.
[0034] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
